Abstract
Implantation necessitates complex interaction among the developing embryo,decidualizing endometrium,and developing maternal immune tolerance or alterations in cellular and humoral immune responses. The local immune tolerance of uterus is critical to successful pregnancy. In physiological condition, granulocyte macrophage colony stimulation factor (GM-CSF) is produced by macrophages, monocytes and endothelial cells. GM-CSF acts on bone marrow for constitutive renewal of myeloid cells. Recently,GM-CSF is recognized as modulator of T cell response, which can improve the formation and attachment of blastocyst. In non-pregnancy stage,uterus epithelium is origin of GM-CSF,which influences the T cell function and induces maternal-fetus tolerance. During first trimester, stromal cells of human placental tissue and maternal decidua produce GM-CSF to regulate reproductive immunology and maintain pregnancy. GM-CSF has been used in treatment of unexplained recurrent miscarriage and thin endometrium. The purpose of this paper is to review the effect mechanism of GM-CSF on endometrium and possible clinical use in reproductive medicine.关键词
